EUA2008
3-W Stereo Class-D Audio Amplifier
with 32-Step DC Volume Control
DESCRIPTION
The EUA2008 is a high efficiency, 2 channel bridged-tied
load (BTL), class-D audio power amplifier. Operating from
a 5V power supply, EUA2008 is capable of delivering 3W/
channel of continuous output power to a 3Ω load with 10%
THD+N. The EUA2008 features a differential input
architecture offering improved noise immunity over a
single-ended (SE) input amplifier. Stereo speaker volume
is controlled with a dc voltage applied to the volume
control terminal offering a range of gain from -38dB to20
dB.
The EUA2008 also features short-circuit and thermal
protection preventing the device from being damaged
during a fault condition. The EUA2008 is available in
thermally efficient 24-pin TSSOP package.
